FIELD

This invention relates generally to leveling and positioning, and morespecifically, to systems and methods for remote leveling andpositioning.

BACKGROUND

Leveling is the positioning of a plane of an object perpendicular to thegravitational axis of the earth; whereas a plane is plumb when it isparallel to the earth's gravitational axis. For example, in a householdsetting, people typically prefer to level pictures, mirrors, and otherframed objects so that these objects are parallel to the floor, ceilingand walls of a house, which are presumed to be level themselves. In aconstruction setting, numerous structural elements must be leveled tosatisfy building codes and esthetic preferences. For example, asdiscussed above, leveling of framed objects requires that structures ofa home be themselves level, which must be done during construction.

Positioning is the placement of an object, which may include itsposition in three dimensional space, or a rotational orientation. Insome situations, positioning may include leveling. An example ofpositioning may include locating an object a certain distance fromanother object, orienting an object toward a compass point, locating theobject a certain distance from sea level or ground level, and the like.

Various devices and methods can be used to level or position an object.One exemplary leveling device is a bubble or spirit level, which is atransparent and slightly curved vial that is incompletely filled withliquid. The resultant bubble in this vial settles to the center of thevial, when the vial is level.

While this is a typical device used to level or plumb objects, it isdeficient because a user must be able to see the position of the bubblein order to properly use the instrument, and being at a distance, atcertain angles, and having an obstructed view makes bubble levelsunusable. Unfortunately, this substantially limits the use of such adevice in many settings.

Additionally, in situations where a plurality of users is leveling anobject, using a bubble level device can be cumbersome because at leastone user must read the level and relay instructions to others. This isnot efficient when an object is heavy or when it is not easy for usersto view the bubble level while working.

The crane operator 905Cand the operator 905B near the crane 900 will perceive the X end asright, and the Y end as left. However, the ground operator 905A willperceive the Y end as right, and the X end as left. Accordingly, theleveling device assembly 100 may be operable to provide leveling orpositioning indications which can be customized to the perspective andposition of various operators 905.

FIG. 10 is a pictorial diagram of a system 1000 of interconnecteddevices, in accordance with various embodiments. The system 1000comprises a leveling device assembly 100 and a plurality of audiodevices 1020A, 1020B, and 1020C, which are operably connected via anetwork 1040. In various embodiments, the network 1040 may be a wirelessnetwork, and the leveling device assembly 100 may be connected to thenetwork 1040 via an antenna 860 (FIG. 8 c) or via a wireless networkinterface, which may be present in a portion of the leveling deviceassembly 100 and/or the leveling device 105.

As described herein, the leveling device assembly 100 may communicateposition status data, leveling data, indications relating to how toachieve a desired leveling position or position, and the like. Suchcommunications may be obtained by an audio device 1020, which maypresent such data or indications in various forms. In some embodiments,an indication relating to how to achieve a desired leveling state orposition may be presented in relation to the location of the audiodevice 1020.

For example, if an audio device 1020 is on a front side of a levelingdevice assembly 100, (i.e. a user is in front of the leveling deviceassembly 100) an indication of “move right side down” may be relevant toan observer in obtaining a level position for the leveling deviceassembly 100. However, if the audio device 1020 is behind the levelingdevice assembly 100 in the same situation, then an indication of “moveleft side down” may be relevant to an observer in obtaining a levelposition for the leveling device assembly 100.

In such examples, there may be a plurality of audio devices 1020 andindications may be modified for each audio device 1020 based on thelocation of a given audio device 1020. In some embodiments, the levelingdevice assembly 100 or audio device 1020 may modify such indicationsbased on obtained audio device location data and level location data.

Audio devices 1020 may be various devices in accordance with someembodiments. For example, a Bluetooth headset, a radio, a cellulartelephone, a personal data assistant, and the like may function as anaudio device 1020. In various embodiments, an audio device 1020 may beany device capable of producing an audio presentation.

FIG. 11 is a pictorial diagram of another system 1100 of interconnecteddevices, in accordance with various embodiments, which comprises aplurality of user devices 1130, an admin device 1110 and a levelingdevice assembly 100, which are all operably connected via a network1040. Additionally, each user device 1130 is operably connected to anaudio device 1020.

As discussed in relation to FIG. 10, various devices may be operablyconnected via a wireless network 1040, and may be connected in variousother ways. In some embodiments, a user device 1130 and audio device1020 may be embodied together in a helmet, an earpiece, a cellulartelephone, a personal data assistant, and the like. Additionally, asdiscussed above, a determination may be made regarding location of anyof an admin device 1110, user device 1130, and audio device 1020, andindications relating to how to achieve a desired leveling status orposition, and the like, may be modified or customized based on such adetermined location of various devices.

In further embodiments, a determination of a danger zone may be made inrelation to objects associated with a leveling device assembly 100,which may include objects being leveled or positioned by the levelingdevice assembly 100. For example, a danger zone may be defined as anarea where an object would fall if it were to be released from acoupling, lose balance, fall down a slope, explode, and the like.

In such embodiments, a danger zone may be determined for an objectassociated with a leveling device assembly 100, and a furtherdetermination may be made whether a given device is located within thedefined danger zone. Where a user device 1130 is located in a defineddanger zone, an alert may be presented via an audio device 1020, aleveling light 325 or laser 315 (FIG. 3), a speaker, and the like. Insome embodiments, such an alert can be provided to a plurality of userdevices 1130, wherein some are within the danger zone or such an alertmay only be provided to user devices 1130 within the danger zone.

In various embodiments, the admin device 1110 may record a leveling orpositioning session, which may include data regarding level position,leveling status, danger zone, position of one or more user device 1130,position of one or more audio device 1020, position of an admin device1110, and the like. In other embodiments, such data may be recorded byany of a leveling device assembly 100, an admin device 1110, a userdevice 1130, an audio device 1020, and the like. In further embodiments,and admin device 1110 may obtain an alert, position data, level-statusdata, define a leveling goal, define a positioning goal, define dangerzone parameters, and the like.

In various embodiments, wherein indications relating to achieving adesired leveling status or position are obtained wirelessly, via anaudio presentation, or via a visual presentation, such embodiments maybe desirable because a leveling device assembly 100 may not beimmediately visible to one or more users because of where the levelingdevice assembly 100 is position on an objected being leveled orpositioned.

For example, a user of a leveling device assembly 100, having only aliquid and bubble leveling body 110, may not be able to view such arelatively small indicator when leveling a post with a tractor orbackhoe. In such an example, it may be desirable to obtain indicationsof position and level status which can be perceived from a distance orthat can be perceived in noisy environments. Here, it may be desirablefor the user to be able to view or hear such indications while drivingthe tractor or backhoe.

In various embodiments, there may be a plurality of level deviceassemblies 100 connected via a network 1040, which may each communicatedata regarding position status or level status to each other, to amaster leveling device assembly 100, to an admin device 1110, to a userdevice 1130, an audio device 1020, and the like. In such embodiments,there may be more than one leveling and/or positioning goal, andindications may be given to facilitate each leveling device assembly 100in reaching its leveling and/or positioning goal.

In some embodiments, adefault leveling goal may be true level, whereas other leveling goals inrelation to true level may be defined 1305.

Level status is determined 1310, and a level status alert is formatted1315 and the level status alert is sent 1320 to the audio device 1020,where the level status alert is presented 1325. For example, a presented1325 status alert may be “rotate clockwise ten degrees”; “move rightside down”; “level goal achieved”; and the like. In further embodiments,level status alert may be formatted 1315 based on a determined locationof an audio device 1020 or other device.

FIG. 14 is a flow diagram illustrating a leveling routine 1400 inaccordance with various embodiments. The leveling routine 1400 begins inblock 1405 where a level goal is defined, which may be defined via aninput on the leveling device assembly 100, or remotely via a user device1130 or admin device 1110. In further embodiments, a default level goalmay be automatically defined as true level.

In block 1410, a level status is determined, which may include degreesor percentage off from level, and the like. In block 1415 a level statusalert is formatted and in block 1420 a level status alert is sent 1420.A level status alert may be sent to another device, to a leveling light120, a speaker 140, and the like.

In decision block 1425 a determination is made whether the levelingsession has ended, and if the leveling session has ended the levelingroutine 1400 ends in block 1499. However, if the leveling session is notended, then the leveling routine 1400 cycles back to block 1410, wherelevel status is again determined.

FIG. 15 is a diagram illustrating the actions taken by a leveling device100 and an audio device 1020 in accordance with various embodiments. Theactions begin where a goal position is defined 1505, and then positionstatus is determined 1510, a position status alert is formatted 1515 andthe position status alert is sent 1520 to the audio device 1020 wherethe position status alert is presented 1530.

In some embodiments a positioning goal may comprise a compass directionor GPS coordinate or be in relation thereto, and may be defined by aninput device on the leveling device assembly 100 or be defined by a userdevice 1130 or an admin device 1110. Additionally, in variousembodiments, the position alert may be formatted 1515 based on anobtained location or position of a user device 1130, admin device 1110,or audio device 1020.

FIG. 16 is a flow diagram illustrating a positioning routine 1600 inaccordance with various embodiments. The positioning routine 1600 beginsin block 1605 where a positioning goal is defined, which may be definedvia an input on the leveling device assembly 100, or remotely via a userdevice 1130 or admin device 1110. In further embodiments, a defaultpositioning goal may be automatically defined as true level or tocomprise true level.

In block 1610, a position status is determined, which may includedegrees or percentage off from level, a GPS coordinate, a distance, andthe like. In block 1615 a position status alert is formatted and inblock 1620 a position status alert is sent 1620.

In decision block 1625 a determination is made whether the positioningsession has ended, and if the positioning session has ended thepositioning routine 1600 ends in block 1699. However, if the positioningsession is not ended, then the positioning routine 1600 cycles back toblock 1610, where position status is again determined. In variousembodiments, a positioning session may end when indicated by a user.

FIG. 17 is a diagram illustrating the actions taken by a leveling device100 and a user device 1130 in accordance with various embodiments. Theactions begin where danger positions are determined 1705. A levelingdevice assembly 100 may be associated with various objects and suchobjects may have characteristics that make them dangerous, such asexplosive, crushing, corrosive, and like properties. For example, alarge sculpture being installed may need to be leveled, but may create arisk for users leveling and installing the sculpture, because it mayfall and crush such a user. Accordingly, in such a situation, a dangerzone may be defined as a radius or area around the sculpture, which maytake into account center of gravity, height, weight, and the like. Sucha defining may be automated or may be defined by a user.

Returning to the actions, the user device 1130 determines 1710 theposition of the user device 1130, and the user device position is sent1715 to the leveling device assembly 100, where a determination 1720 ismade whether the device position is equal to a danger position orwhether the device position is within a danger zone or area. A dangerposition alert is formatted 1725 and sent 1730 to the user device 1130,where the danger position alert is presented 1735.

In various embodiments, there may be a plurality of user devices 1130and each user device 1130 may be sent 1730 the same danger positionalert or a danger position alert may be custom formatted 1725 and sent1730 each user device 1130 based on user device location and identity.For example, if a first user device 1130A is in a danger zone, the firstuser device 1130A may be sent 1730 a danger position alert such as “UserDevice A, you are in a danger zone!”; however, a second user device1130B may not be sent 1730 a danger position alert or may be sent adanger position alert such as “Use device A is in a danger zone!”Accordingly, devices may be alerted to their own danger, to the dangerof other devices, and the like.

FIG. 18 is a flow diagram illustrating a device danger alert routine1800 in accordance with various embodiments. The device danger alertroutine 1800 begins in block 1805 where danger positions are determined,and in block 1810, a user device position is obtained.

In decision block 1815 a determination is made whether the user device1130 is in a danger position. In various embodiments, such adetermination may be made by comparing the obtained user device positionto the defined danger positions. If the user device 1130 is not in adanger position the device danger alert routine 1800 continues to block1830, where a determination is made whether the danger position alertsession has ended. However, if the user device 1130 is in a dangerposition, then the device danger alert routine 1800 continues to block1820, where a danger position alert is formatted. In block 1825 thedanger alert is sent to the user device 1130.

In decision block 1830 a determination is made whether the dangerposition alert session has ended, and if so, the device danger alertroutine 1800 is done in block 1899. However, if the danger positionalert session is not ended, then the device danger alert routine 1800cycles back to block 1805, where danger positions are again determined.

For example, in various embodiments, danger positions and user devicepositions can be continually determined and/or obtained. Dangerpositions may change as an object associated with the leveling deviceassembly 100 changes positions, or as the object associated with theleveling device assembly 100 changes level status. When it is determinedthat the user device 1130 is in a danger position, an alert can beformatted and sent to the user device 1130 so as to warn a user. Thiscan be done continually in real time or at defined intervals during adanger position alert session.

The following FIGS. 19, 20 and 21 depict various embodiments of levelingdevice assembly 100 networks, and uses thereof. In such embodiments, anetwork of leveling device assemblies 100 may be networked via awireless network, and may also be connected to various other devices orservers via a wireless network, the internet, or the like.

FIG. 19 depicts a plurality of leveling device assemblies 100 positionedat various intervals along both sides of a road. Adjacent levelingdevices form a plurality of triangular motion planes 1950, which may beused to model the movement of portions of the road and ground withineach plane 1950 and which collectively form a matrix 1900. For example,motion plane 1950 ₁ is defined by imaginary lines connecting levelingdevice assemblies 100 ₁, 100 ₆, and 100 ₇. Motion plane 1950 ₂ isdefined by imaginary lines connecting leveling device assemblies 100 ₁,100 ₂, and 100 ₇.

Each leveling device assembly 100 may obtain positioning and level data,which may be used to model movement of each motion plane within thematrix 1900 and thereby model movement of the road and ground as awhole. Additionally data such as accelerometer data, and temperaturedata may also be obtained.

In an embodiment, data collected or modeled from a matrix 1900 can bepresented to various users. For example, road signs may present imagesthat reflect road conditions in real time, which may be based on dataobtained from the matrix 1900. Additionally, such data collected fromthe matrix 1900 can be used by transportation agencies to determine whena road surface may need immediate repair or future repair.

Similarly, FIG. 20 depicts a matrix 2000 comprising a plurality ofleveling device assemblies 100, which also forms a plurality of motionplanes (not labeled). As shown in FIG. 20, the leveling deviceassemblies 100 are positioned in various locations on a mountain range,and the motion planes may be various shapes and sizes.

Accordingly, in an acute seismic event, or over time, the pitch and yawlof each plane may reveal a relationship between planes that may nototherwise be observable with other types of point measurement. A matrix2000 as in FIG. 20 may be applied to locations with seismic activity toreveal shadows of tectonic interaction and movement that may nototherwise be observable by other seismic systems. Such measurements andmodeling may be useful in the prediction of acute seismic events such asearthquakes.

In embodiments where leveling device assemblies 100 are positioned inand about the ground or ground features, a leveling device assembly 100may housed within a hollow cylinder oriented perpendicular to the groundor the gravitational axis. Such cylinders may house the leveling deviceassembly 100 at, above, or below grade.

FIG. 21 depicts a plurality of leveling device assemblies 100 positionedat various points on a bridge. Here, each leveling device assembly 100may provide positioning, leveling, seismic, and acceleration data, whichmay be associated or attributed to a portion, part or plane of thebridge on which the leveling device assembly 100 is positioned.

Accordingly, based on data obtained from the leveling device assemblies100, modeling of the movement, strain, and position of the bridge may beachieved in various embodiments. For example, various parts of thebridge may be identified as being high or low strain areas, which may becorrelated with traffic volume, or temperature changes. Such modelingmay be used to determine areas or parts of the bridge that are in needof repair, or that need to be reinforced to prevent damage orcatastrophic failure of the structure. In further embodiments, such anetwork of leveling device assemblies 100 may be applied to variousstructures.

FIGS. 22 a and 22 b are a side view of a positioning sphere 2200 inaccordance with various embodiments. FIG. 22 a depicts the positioningsphere 2200 in a level position, and FIG. 22 b depicts the positioningsphere in a non-level position. The positioning sphere 2200 comprises adata ball 2210, which is suspended in a suspension media 2230 andcontained within a shell 2225. The data ball 2210 may rotate freelywithin the suspension media 2230 and shell 2225. Additionally, the shell2225 is coupled to a leveling plate 2235, which is an extendedsubstantially flat member.

In some embodiments, the surface of the data ball 2210 is encoded withdata, which relates to a position on the data ball 2210. For example,the surface of the data ball 2210 may be encoded with data like acompact disc (“CD”), digital versatile disc (“DVD”), BlueRay disc, andthe like, which can be read by the laser 2255 of a reader 2250.Accordingly, as the data ball 2210 rotates within the suspension media2230, the change in position can be tracked as the reader 2250 reads thedata that passes in view of the laser 2255.

In some embodiments, the data ball 2210 comprises a gravity body 2245,which is a body that is heavier than other portions of the data ball2210 and therefore the gravity body 2245 is attracted to the earth'sgravitational center via a gravitational force 2265. Accordingly, avertical plane 2215 of the data ball 2210 is kept in alignment with theearth's gravitational center despite movement of the shell 2225 orstructures attached thereto such as the leveling plate 2235.

In further embodiments the data ball 2210 comprises a compass body 2240,which is a magnetized body that is attracted to the earth's polar north.Accordingly, the compass body 2240 will be attracted to polar north viamagnetic forces 2260 and a plane of the data ball 2210 will be alignedalong a horizontal axis 2220 to magnetic north despite any change inposition of the shell 2225 and structures attached thereto such as theleveling plate 2235.

FIG. 22 a depicts the positioning sphere 2200 in a level position asindicated by the leveling plate 2235 being parallel to depictedhorizontal axis 2220, and FIG. 22 b depicts the positioning sphere in anon-level position, as indicated by the leveling plate 2235 not beingparallel to depicted horizontal axis 2220. However, despite the levelingplate 2235 and shell 2225 being in a different position, the data ball2210 retains the same orientation and alignment because the gravity body2245 remains attracted to the earth's gravitational center viagravitational forces 2265, and the compass body 2240 remains orientedtoward magnetic north via magnetic forces 2260.

In various embodiments, the position on the data ball 2210 being read inFIG. 22 a by the reader 2250 may be considered a desired or zeroposition because the leveling plate 2235 is level, and the compass body2240 naturally orients the data ball 2210 toward magnetic north.Accordingly, any changes in position from such a desired state may betracked as the data ball 2210 rotates in relation to the reader 2250.

In some embodiments, the desired position may be changed. For example, aposition wherein the leveling plate 2235 is perpendicular to level orany other orientation may be defined as a desired position or zeroposition.

FIG. 24 shows a perspective view of a leveling device assembly 100K inaccordance with an embodiment. The leveling device assembly 100Kcomprises housing 2400, which may comprise a first, second, third andfourth face 2405, 2410, 2415, 2420. The first face 2405 may include anelongated sloped trench 2425, which extends from a first end 2445 to asecond end 2450. The second and third faces 2410, 2415 may comprise anelongated coupling slot 2435A, 2435B respectively. The fourth face 2420may include an angular notch 2430 that extends from the first end 2445to the second end 2450. The housing 2400 may comprise one or more devicecavity 2440A, 2440B.

In an embodiment, the housing 2400 may have a substantially cuboidprofile aside from features such as the sloped trench 2425, angularnotch 2430 and one or more coupling slot 2435A, 2435B. For example thefirst, second, third and fourth face 2405, 2410, 2415, 2420 and firstand second end 2445, 2450 may have a substantially rectangular profile,and where the first, second, third and fourth face 2405, 2410, 2415,2420 and first and second end 2445, 2450 are square to other and meet ata right angle. Such a configuration may be desirable in and embodimentbecause it makes each side of the leveling device assembly 100K operableto engage a planar surface so that the level status of the planarsurface may be detected and indicated by the leveling device assembly100K.

Additionally, in an embodiment, it may be desirable to detect the levelstatus of objects that are non-planar, or to detect the level status ofcorners, or the like. Accordingly, in an embodiment, sloped trench 2425and angular notch 2430 may make the leveling device assembly 100Koperable to engage non-planar objects or features.

For example, the sloped trench 2425 may be configured to engage varioussizes of cylindrical objects. The sloped trench 2425 may be uniformalong its length extending from the first end 2445 to the second end2450 and being aligned with a central axis of the first face 2405.

In an embodiment, the curve of the sloped trench 2425 may be a Witch ofAgnesi curve having the Cartesian equation y(x²+a²)=a³ or the parametricequation of x=at, y=a/(1+t²). The Witch of Agnesi curve may be desirablein some embodiments because it may provide stability when coupled withcylindrical objects, while providing the ability to couple withcylindrical, ovoid, or curved objects having a wide range of diameters.Although the Witch of Agnesi curve may be desirable in some embodiments,any other suitable curve or substantially curved profile may be employedin other embodiments.

The angular notch 2430 may be configured to engage angular objects andsurfaces, such as a corner where planar faces meet. The angular notch2430 may be uniform along its length extending from the first end 2445to the second end 2450 and being aligned with a central axis of thefourth face 2420. In one embodiment, a notch central apex 2431 maydefine a 90° angle.

In some embodiments the angular notch 2430 and sloped trench 2425 may beon opposing faces of the housing 2400. Additionally, the angular notch2430 and sloped trench 2425 may also be aligned in a similar plane. Forexample, a trench central apex 2426 of the sloped trench 2425 may bealigned with the notch central apex 2431 in a common location. In someembodiments, the angular notch 2430 and sloped trench 2425 may not bealigned or may not be on opposing faces.

One or more coupling slot 2435A, 2425B may be located on one or moreface 2405, 2410, 2415, 2420. In an embodiment, coupling slots 2435A,2435B may be an elongated slot that extends from the first end 2445 tothe second end 2450. The coupling slots 2435A, 2425B may comprise a slotopening-passage 2436 and a slot inner-cavity 2437.

The slot opening-passage 2436 may be narrower than the slot inner-cavity2437. For example, as depicted in FIG. 24, the slot opening-passage 2436may be a substantially uniform rectangular opening, which extendsinwardly and opens up into the slot inner-cavity 2437, which may bewider than the slot opening-passage 2436.

The leveling device assembly 100K may further include a coupling pin2455A, which is configured to couple with the housing 2400 via couplingslots 2435A, 2425B. The coupling pin 2455A may comprise a coupling-pinhead 1456, a coupling-pin shaft 2457, and a coupling-pin bow 2458. In anembodiment, the coupling-pin head 1456 is configured pass within theslot opening-passage 2436 in a first orientation and configured tocouple within the slot inner-cavity 2437 in a second orientation. Thecoupling pin 2455A may be inoperable to pass within the slotopening-passage 2436 in the second orientation.

For example, the coupling-pin head 1456 may have a length thatcorresponds to the height of the slot inner-cavity 2437, and thecoupling-pin head 1456 may have a width that corresponds to the heightof the opening-passage 2436. When inserting the coupling pin 2455A intothe slot opening-passage 2436 the coupling-pin head 1456 may be orientedsuch that the coupling-pin head 1456 may slide within the slotopening-passage 2436 and into the slot inner-cavity 2437. The couplingpin 2455A may then be rotated (e.g., 90°) such that the lengthcoupling-pin head 1456 turns to engage the slot inner-cavity 2437. Thecoupling pin 2455A may thereby be coupled or held within a coupling slot2435A, 2425B.

In an embodiment, the coupling of one or more coupling pin 2455A withinone or more coupling slots 2435A, 2425B may facilitate the levelingdevice assembly 100K being secured to or coupled with various objects.For example, a first and second coupling pin 2455A may be coupled onopposing faces of the housing 2400 via coupling slots 2435A, 2425B, andan elastic band may extend between the first and second coupling pin2455A. The elastic band may extended around various object (e.g., pipes,beams, or the like), such that the leveling device assembly 100K can becoupled or held thereto.

In other embodiments, a coupling pin 2455A may include additionalfeatures or structures, which provide for coupling of the levelingdevice assembly 100K to various objects. For example, FIGS. 25 a, 25 band 25 c depict embodiments of a coupling pin 2455B, 2455C and theleveling device assembly 100K of FIG. 24. For example, FIG. 25 b depictsan embodiment of a coupling pin 2455B, which includes an extendedcoupling arm 2458. FIG. 25 a depicts a first and second coupling pin2455B coupled within coupling slots 2435A, 2425B (FIG. 24). The couplingarms 2458 of the first and second coupling pin 2455B may be operable toattach to various objects, such as a pipe, or the like.

In another embodiment, as depicted in FIG. 25 c, the housing 2400 may beheld against a surface by a suction coupling pin 2455C. The suctioncoupling pin 2455C may comprise a suction arm 2510, a suction cup 2520,and a soft shoe 2530 at a distal end of the suction arm 2510. Forexample, the suction coupling pin 2455C may be operable to couple with asurface such as glass, and allow the housing 2400 to be held thereto.

The housing 2400 may define one or more one or more device cavity 2440A,2440B. For example, FIG. 24 depicts a first and second device cavity2440A, 2440B, which extend from the first end 2445 to the second end2450. In some embodiments, one or more first and second device cavity2440A, 2440B may house a portion of a leveling device (not shown in FIG.24), which may have any suitable components, features, abilities, or acombination thereof, as described herein in one or more embodiments. Forexample, a leveling device disposed within the housing 2400 may comprisevarious leveling, positioning, and acceleration functionalities. Aleveling device disposed within the housing 2400 may comprise elementssuch as a compass, a leveling body, a global positioning system (GPS),an accelerometer, an electronic timing device, a compass device, anazimuth-finding device, a vector detecting device, image capturingdevice, audio recording device, and the like. However, in someembodiments, a leveling device 105 may lack one or more of thesefunctionalities and related functional elements, and may merely be aprocessor or computer.

The housing 2400 may also be magnetic. For example, the housing maycomprise a magnetic portion 2488 on any of the faces 2405, 2410, 2415,2420 or ends 2445, 2450. In an embodiment, the housing 2400 may comprisea plurality of magnetic strips 2488 that may be oriented parallel orperpendicular to the axies of faces 2405, 2410, 2415, 2420 or ends 2445,2450. In one embodiment, a plurality of magnetic strips 2488 may bedisposed on the first face 2405, which at least extend from the secondface 2410 to the third face 2415 and parallel to the first and secondend 2445, 2450.

In some embodiments, corners where faces 2405, 2410, 2415, 2420 or ends2445, 2450 meet may be rounded or truncated. For example, such a cornermay be flatly, convexly, or concavely truncated. Such an embodiment maybe desirable because it may allow the housing 2400 to be adaptable toengage with a wider variety of surfaces and object contours.

In some embodiments, caps (not shown) may be operable to cover andengage with the ends 2445, 2450. Such caps may include an extension ofcoupling slots 2435A, 2535B and my also conform to the profile of theends 2445, 2450. In an embodiment, caps on the ends 2445, 2450 mayprovide a water-tight or air-tight seal between the device cavities2440A, 2440B and the external environment. In an embodiment, caps on theends 2445, 2450 may support a vacuum or positive pressure within thedevice cavities 2440A, 2440B with respect to the outside environment.

FIGS. 26 a and 26 b show perspective views of a leveling device assembly100L in accordance with a further embodiment. The leveling deviceassembly 100L comprises a housing 2600, which may comprise a first,second, third and fourth face 2605, 2610, 2615, 2620. The first face2605 may include an elongated sloped trench 2625, which extends from afirst end 2645 to a second end 2650. The second and third faces 2610,2615, or sidewalls, may comprise an elongated coupling slot 2635A, 2635Brespectively. The fourth face 2620, or base, may comprise a squaringplate 2621 that is slidably coupled about the base 2620 and alsocomprise a base lip 2622.

The squaring plate 2621 may be substantially planar and operable toassume an extended position wherein the squaring plate 2621 extendsperpendicular to and past a face of at least one sidewall 2610, 2615(e.g., as depicted in FIGS. 26 a, 26 b, 27 and 32 a). The squaring plate2621 may also be operable to assume a stowed position wherein thesquaring plate 2621 is disposed between the sidewalls 2610, 2615 (e.g.,as depicted in FIGS. 28 a, 28 b, 29 b and 32 b). In the extendedconfiguration, the squaring plate 2621 and sidewall 2610 may define asquaring corner 2623, which as shown in FIG. 27, may be used to squarethe device 100L to an edge 2705 of an object 2710.

The squaring plate 2621 may be slidably coupled at the base 2620 via anysuitable structure including a pin-in-slot configuration, or the like.In some embodiments, the squaring plate 2621 may be spring loaded. Thesquaring plate 2621 can be any suitable size in various embodiments, andmay include any suitable edge. The squaring plate 2621 may also compriseone or more suitable material. For example, in some embodiments, thesquaring plate 2621 may comprise a metal rail embedded in the frontprotruding edge of the body of the squaring plate 2621, which acts as astraight-edge.

In an embodiment, the housing 2600 may have a substantially cuboidprofile aside from features such as the sloped trench 2625 and one ormore coupling slot 2635A, 2635B. For example the, sidewalls 2610, 2615and base 2620 and first and second end 2645, 2650 may have asubstantially rectangular profile, and where the, second, third andfourth face, 2610, 2615, 2620 and first and second end 2645, 2650 aresquare to each other and meet at a right angle. In a stowedconfiguration, the squaring plate 2621 and base lip 2622 may define asubstantially contiguous base-face 2620 that extends between thesidewalls 2610, 2615 and between the first and second ends 2645, 2650.In various embodiments, however, the base lip 2622 may be absent and thesquaring plate 2621 may define a substantially contiguous base-face2620.

Such a cuboid and squared configuration may be desirable in anembodiment because it makes each side of the leveling device assembly100L operable to engage a planar surface so that the level status of theplanar surface may be detected and indicated by the leveling deviceassembly 100L.

Additionally, in an embodiment, it may be desirable to detect the levelstatus of objects that are non-planar, or to detect the level status ofcorners, or the like. Accordingly, in an embodiment, the sloped trench2625 may make the leveling device assembly 100L operable to engagenon-planar objects or features.

For example, the sloped trench 2625 may be configured to engage varioussizes of cylindrical objects as depicted in FIGS. 30 and 32 a. Thesloped trench 2625 may be uniform along its length extending from thefirst end 2645 to the second end 2650 and being aligned with a centralaxis of the first face 2605.

One or more coupling slots 2635A, 2635B may be located on one or morefaces 2605, 2610, 2615, 2620. In a preferred embodiment, matchingcoupling slots 2635A, 2635B may be respectively disposed on thesidewalls 2610, 2615. In one embodiment, coupling slots 2635A, 2635B maybe an elongated slot that extends from the first end 2645 to the secondend 2650. The coupling slots 2635A, 2625B may comprise a slotopening-passage 2636 and a slot inner-cavity 2637.

The slot opening-passage 2636 may be narrower than the slot inner-cavity2637. For example, as depicted in FIGS. 26 a and 26 b, the slotopening-passage 2636 may be a substantially uniform rectangular opening,which extends inwardly and opens up into the slot inner-cavity 2637,which may be wider than the slot opening-passage 2636.

In an embodiment, the sloped trench 2625 may define an elongatedcoupling slot 2626 disposed at the central apex of the sloped trench2625. In some embodiments, the coupling slot 2626 of the sloped trench2625 may have the same size and/or profile as the coupling slots 2635A,2635B on the sidewalls 2610, 2615, but in some embodiments the sizeand/or profile may be different. For example, as depicted in FIGS. 26 aand 26 b, the coupling slots 2635A, 2635B may have a rectangularprofile, whereas the coupling slot 2626 may have a circular profile.

The housing 2600 may define one or more device cavity (not shown). Insome embodiments, the one or more device cavity may house a portion of aleveling device (not shown in FIG. 26), which may have any suitablecomponents, features, abilities, or a combination thereof, as describedherein in one or more embodiments. For example, a leveling devicedisposed within the housing 2600 may comprise various leveling,positioning, and acceleration functionalities. A leveling devicedisposed within the housing 2600 may comprise elements such as acompass, a leveling body, a global positioning system (GPS), anaccelerometer, an electronic timing device, a compass device, anazimuth-finding device, a vector detecting device, image capturingdevice, audio recording device, and the like. However, in someembodiments, a leveling device may lack one or more of thesefunctionalities and related functional elements, and may merely be aprocessor or computer.

The housing 2600 may also be magnetic. For example, the housing maycomprise a magnetic portion 2688 on any of the faces 2605, 2610, 2615,2620 or ends 2645, 2650. In an embodiment, the housing 2600 may comprisea plurality of magnetic strips 2688 that may be oriented parallel orperpendicular to the axes of faces 2605, 2610, 2615, 2620 or ends 2645,2650. In one embodiment, a plurality of magnetic strips 2688 may bedisposed on the first face 2605, which at least extend from the secondface 2610 to the third face 2615 and parallel to the first and secondend 2645, 2650.

In some embodiments, corners where faces 2605, 2610, 2615, 2620 or ends2645, 2650 meet may be rounded or truncated. For example, such a cornermay be flatly, convexly, or concavely truncated. Such an embodiment maybe desirable because it may allow the housing 2600 to be adaptable toengage with a wider variety of surfaces and object contours.

In addition to appliances like a coupling pin 2455, coupling pin withextended arm 2455B, or suction coupling pin 2455C as depicted in FIGS.24 and 25 a-c (which are equally applicable to the housing 2600),various other appliances or accessories may be applied to and used withthe housing 2600 (or housing 2400) in various embodiments.

For example, FIGS. 28 a and 28 b depict a coupling bracket 2805 thatincludes a first and second arm 2808A, 2808B and span 2807 that define acoupling cavity 2808. The coupling bracket 2805 also includes a pin 2809that is configured to couple with the coupling slots 2635 and in someembodiments with center coupling slot 2626. The pin 2809 may be operableto rotatably enter and couple with the slot 2635 along its length asdescribed herein, or may be configured to only enter a slot 2635 at thefirst or second end 2645, 2650. In other words, the dimensions of thepin 2809 may not be configured for rotatable coupling via the length ofa slot 3635 in some embodiments.

As depicted in FIG. 28 b, for example, coupling brackets 2805A, 2805Bmay be configured to couple with dimensional lumber 2810 and therebycouple the housing 2600 to the dimensional lumber 2810 along a parallelaxis. Use of one or a plurality of coupling brackets 2805 may bedesirable. Accordingly, the generally U-shaped coupling cavity 2808 maybe configured to correspond to various standard dimensional lumber sizesincluding 2-by, 4-by, and the like. In further embodiments, the arms2806 and/or span 2807 may be configured to assume different sizes or maybe elastic. Additionally, while the pin 2809 is depicted as beingcoupled to the first arm 2806A, it may alternatively be coupled with thespan 2807, or may be coupled to any portion of the arms 2806 or span2807 in any suitable configuration or orientation. Coupling brackets2805 may also be configured to couple with various cuboid, circular, orirregularly shaped objects.

For example, FIGS. 29 a and 29 b depict a coupling bracket 2905 that isconfigured to couple with a circular pipe 2910. The coupling bracket2905 comprises arms 2906 that define a crescent-shaped coupling cavity2808 that is configured to couple with circular objects such as a pipe2910. A limb 2907 extends from a portion of the arms 2906 and includes acoupling pin 2909 at a distal end, which is configured to couple with acoupling slot 2635 of the housing 2600 as discussed herein. In variousembodiments, one or more coupling bracket 2905 may be used to couple thehousing 2600 with an object.

The coupling bracket 2905 may be various suitable sizes to accommodatevarious sizes of circular, oval or other shaped objects. Additionally,in various embodiments, the arms 2906 of the coupling bracket 2905 maybe elastic, magnetic, or comprise a surface is that is configured toprovide for improved coupling with objects. For example, the arms 2906may be elastic or biased toward the center of the coupling cavity 2908to provide for gripping to an object. The arms 2906 may also compriserubber, silicone, an adhesive or textured surface that provides forgripping to desired objects such as a pipe 2910. Additionally, while thelimbs 2907 are shown configured to extend parallel to a tangent of thearms 2906, in further embodiments, the limbs 2907 may extend at variousdesirable angles or directions. The limbs 2907 may also be rotatablycoupled to the arms 2906 so as to provide for customized extensiondirection of the limbs 2907.

The housing 2600 may be coupled directly to objects in accordance withsome embodiments. For example, FIGS. 30 a and 30 b depict a couplingstrap 3005 that is operable to surround a portion of an object andthereby couple the housing 2600 to the object. The coupling strap 3005comprises an elongated strap body 3006 with coupling pins 3009 on theends of the strap 3006. The coupling pins 3009 may be configured tocouple with coupling slots 2635 as discussed herein and thereby define acoupling loop 2908 that surrounds an object and thereby couplesthehousing 2600 to the object. For example, FIG. 30 a depicts a pair ofcoupling straps 3005A, 3005B that are encircling a pipe 2910, with thepipe 2910 residing within the sloped trench 2625 defined by the housing2600 and within the coupling loops 2908 defined by the respective straps3005.

In various embodiments, a portion of the coupling strap 3005 may beelastic so the coupling strap 3005 can accommodate various sizes ofobjects and so that the object can be held securely within the slopedtrench 2625, or against other faces of the housing 2600 such as thesidewalls 2410, 2415 or base 2420.

FIGS. 31 a-d depict various embodiments 3105A, 3105B, 3105C of acoupling base 3105. The coupling base 3105 comprises a base member 3106having a limb 3107 extending therefrom, with a coupling pin 3109disposed at a distal end of the limb 3107. The coupling pin 3109 may beconfigured to couple with one or more coupling slot 2635 as discussedherein. In some embodiments, (e.g., 3105A, and 3105C, the base member3106 may define one or more coupling holes 3108. In various embodiments,the coupling holes 3108 may be used to secure the base member 3106 to anobject via screws, nails, or the like. In further embodiments, the basemember 3106 may couple with desired objects in other ways. For exampleFIG. 31 c depicts a coupling base 3105B having a magnet 3111. In furtherembodiments, a coupling base 3106 may include an adhesive, suction cup,hook, stake, or other desirable coupling structure.

In various embodiments, (e.g., 3105A, and 3105B) the limb 3107 and pin3109 may be configured to couple the housing 2600 substantially parallelto the coupling base 3106, however, in some embodiments (e.g., 3105C),the limb 3107 and pin 3109 may be configured to couple the housing 2600at an angle that is not parallel to the coupling base 3106. In someembodiments, such a coupling orientation or angle may be static;however, in other embodiments, the limb 3107 and/or pin 3109 may berotatably coupled to the coupling base 3106 such that a desiredorientation of the housing 2600 may be achieved. For example, the angleof the housing 2600 relative to the base 3106 may be configured, or therotation orientation of the housing 2600 at a given angle may beconfigured.

As discussed herein (and as depicted in FIG. 3 a, for example), ahousing 2600 or leveling device 100 may comprise one or more laserassembly 3215 that is configured to project a laser 3220 coincident withan axis of the housing 2600. FIG. 23 a depicts a housing 2600 thatcomprises a laser assembly 3215 that is configured to project a laser3220A extending from the first end 3245 of the housing 2600 that iscoincident with a housing axis extending between the first and secondend 3245, 3250. A second laser 3220B is depicted being projected fromthe second end 3250 by a second laser assembly (not shown). Such aconfiguration may be desirable because the lasers 3220 may represent anaxis that is parallel to an axis of an object associated with thehousing 2600 (e.g., the pipe 2910 disposed in the sloped trench 2625 ofthe housing 2600). The configuration of laser assemblies 3215 depictedin FIG. 32 a is only an example, and as discussed herein, lasers 3220may be projected from any suitable portion of the housing 2600 and mayrepresent various suitable axes.

FIG. 32 b depicts a housing 2600 with a removable laser appliance 3205coupled to the housing 2600 via the coupling slot 2626 at the center ofthe sloped trench 2625. The laser appliance 3205 comprises a laserappliance body 3206 that conforms to the walls of the sloped trench 2625and includes a coupling pin 3209 that is configured to couple within thecoupling slot 2626 as described herein. A laser assembly 3215 isdisposed on a top end of the body 3206 and is configured to project afirst and second laser toward and past the first and second ends 3245,3250 respectively, along a common axis that is coincident with an axisof the housing 2600. In some embodiments, the laser assembly 3215 may bedisposed in any suitable portion of the body 3206 including at a centrallocation or as a portion of the pin 3209. In some embodiments, a laserappliance 3205 may be configured to couple with the housing 2600 inother places. For example, a laser appliance may couple within or aboutone or more of the coupling slots 2635 on the sidewalls 2610, 2615 ofthe housing 2600.

Housings 2400, 2600 are shown as example embodiments of housings inaccordance with the present invention; however, these example housings2400, 2600 should not be construed to limit the many variations of thesehousings that are within the scope and spirit of the present invention.For example, any of the disclosed portions of the housings 2400, 2600may be absent, in plural, or interchanged among embodiments as desired.Disclosure related to one embodiment is equally applicable to disclosurerelated to another embodiment. Appliances discussed herein may also beadapted to any suitable housing embodiment.
